Эвристика — практический метод или правило, используемое для быстрого или приближенного решения задачи, когда точные методы слишком затратны, медленны или недоступны. В ИИ и поиске эвристики часто направляют решения, обменивая часть оптимальности, полноты или точности на скорость и удобство использования.
A technique designed for solving a problem more quickly when classic methods are too slow, or for finding an approximate solution when classic methods fail to find any exact solution. This is achieved by trading optimality, completeness, accuracy, or precision for speed. In a way, it can be considered a shortcut. A heuristic function, also called simply a heuristic, is a function that ranks alternatives in search algorithms at each branching step based on available information to decide which branch to follow. For example, it may approximate the exact solution.
A simple and quickly implemented solution to a problem. For example, "With a heuristic, we achieved 86% accuracy. When we switched to a deep neural network, accuracy went up to 98%."
